Transitioning from gi to no gi

I train/compete BJJ but in a gi. I've recently started no gi and with the grips taken away, I struggle to control opponent and set up subs, esp basic ones like arm bar from guard.
Any little techniques that will help me improve my no gi game?

1. What is the arm connected to? The shoulder.
2. Where does the elbow go when they pull it out of your armbar attempt? backwards of course.

Therefore, what you need to do (gi or not!) is:
1. keep their posture broken, so the shoulder is down low
1.b. lock that shoulder tight with your leg clamp and high guard
2. make sure your legs/guard are tight and your (left) thigh is tight behind their (right) elbow so it can't go anywhere.

some say the no gi game is looser. I think the exact opposite. you need to be much tighter with your under- and overhooks and clinch in no gi.

Enjoy!
